6.1 Optimization of Picture Settings

All common video modes are pre-installed in an internal table of the
Media- / DVI-Converter. If the input signal corresponds to one of these
video modes, the signal will be automatically detected and the picture will
be displayed.

If picture quality is not satisfying or no picture is displayed, proceed as
follows:

1. Optimize the output settings (see Chapter 6.1.1, Page 36). Thus, the
picture d

isplay will be adapted to the properties of the monitor.

2. Optimize the input settings (see Chapter 6.1.2, Page 36). Check if the
automatic

ally detected video mode corresponds to your input signal.
Alternatively, you can manually select the most suitable video mode,
even if you have an unknown input signal.

3. Optimize the picture settings for your input signal (see Chapter 6.1.3,
Page 37).

In some cases it might happen that none of these measurements leads to
a satisfying result. In this case fill in the video mode questionnaire
(Download

) so that a customer specific video mode can be created.

K238 Media- / DVI-Converter

6.1.1 Optimization of Output Settings

1. If you have an analog input signal, display a picture with as much
detail as possible on your graphic source, e.g. a text with black letters
on a white ground (or vice versa).

2. Open the OSD with the infrared remote control.

3. Select 'Output Settings' in the main menu (see Chapter 5.2.4,
Page 30).

4.

Select the output resolution in the menu item 'Output':
– Select 'DDC' to use the preferred resolution of the monitor DDC.
– If the preferred resolution of the device DDC does not result in a

satisfying picture, select 'Factory' and from the menu item
'Resolution' the most suitable resolution for the monitor.

5. Exit the OSD.
A window appears to save settings. This may take a few seconds.

6. Save the settings.

6.1.2 Optimization of Input Settings

For certain analog input signals (VGA / RGB / EGA), if the picture quality
is not satisfying or no picture is displayed, you can select a video mode
depending on the input signal.

1. Open the OSD with the infrared remote control.

2. Select 'Input Settings' in the main menu (see Chapter 5.2.3, Page 29).

3.

Test the recommended resolutions that are listed in the menu item
'Select Resolution'. The menu item is inactive, if there is only one
recommended resolution.

4. Run the automatic picture adjustment:
– Select 'Picture Settings' in the main menu (see Chapter 5.2.2,

Seite 26).

–

Select the menu item 'Auto Configuration'. Thereby picture size
might change.

5. Check the test picture: If the vertical lines are displayed clearly,
without smear or tremble, the setting has been successful.

6. Exit the OSD.
A window appears to save settings. This can take a few seconds.

7. Save the settings.

Operation

6.1.3 Optimization of Picture Settings

For certain analog input signals (VGA / RGB / EGA), if the picture quality
is still not satisfying after the automatic picture adjustment, you can adjust
clock and phase manually.

1. Select 'Picture Settings' in the main menu.

2. Modify the values in the menu items 'Clock' and 'Phase' until all
failures have disappeared.

3. If the picture is displaced:
– Select the menu item 'Display position' in the main menu item

'Output Settings' and position the picture in the upper left corner
of the monitor.

– Select the menu items 'Width' and 'Height' in the main menu item

'Picture Settings' and modify the values for width and height of
the picture until the monitor is completely filled by the picture.

4. Exit the OSD.
A window appears to save settings. This can take a few seconds.

5. Save the settings.

6.2 Download of DDC Information

Loading DDC information is only relevant if you want to connect a DVI or
VGA source. By default, the factory DDC information is reported to the
source (computer, CPU). If these settings do not lead to a satisfying result,
the DDC information of the connected monitor can be downloaded and
stored internally.

There are two options to load the DDC information of the connected
monitor:

 By means of the infrared remote control (see Chapter 6.2.1,

Page 38).



By means of the 'Read DDC' command in the OSD (see
Chapter 6.2.2, Page 38).

6.2.1 Download of DDC by Infrared Remote Control

1. Press the <DDC> button on your infrared remote control.

2. Save the DDC as DVI or VGA DDC matching the input video signal.
The DDC information of the connected monitor is saved in the Media- /

DVI-Converter in the selected format.
The source (computer, CPU) can read the DDC information of the

monitor and display the available video resolutions.

6.2.2 Download of DDC via OSD

1. Open the OSD with the infrared remote control.

2. Select 'General Settings' in the main menu (see Chapter 5.2.5,
Page 31).

3.

Select the menu item 'Read DDC' in the submenu 'DDC'.

4. Save the DDC as DVI or VGA DDC matching the input video signal.
The DDC information of the connected monitor is saved in the Media- /

DVI-Converter in the selected format and is displayed at the bottom of
the OSD menu under 'DEV:'.

The source (computer, CPU) can read the DDC information of the
monitor and display the available video resolutions.

10.2 North American Regulatory Compliance

This equipment has been found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.

Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.

Shielded cables must be used with this equipment to maintain compliance
with radio frequency energy emission regulations and ensure a suitably
high level of immunity to electromagnetic disturbances.

All power supplies are certified to the relevant major international safety
standards.
